Quizplus · Accepted Answer

Atolls are coral reefs that have formed around a submerged volcanic island. Over time, as the island sinks or erodes away, the coral reef continues to grow and form a circular or horseshoe-shaped ring around a lagoon. This process is known as erosion and submergence, making choice A the best answer.
